This design, with its many facets, is designed for large clear quartz. It has surprisingly good light return for its L/W ratio, and has amazing tilt brightness. Be careful! This design has multiple sets of codependent meetpoints (areas where, within one step, a single facet hits multiple meetpoints). Suggested size = 20+ mm
